Palladium-catalyzed Borylation of Aryl Arenesulfonates with Dialkoxyboranes

Palladium-catalyzed Borylation of Aryl Arenesulfonates with Dialkoxyboranes

The cross-coupling of aryl arenesulfonates with dialkoxyboranes proceeded in the presence of Bu4NI and a catalytic amount of [Pd(dba)2]/1,1′-bis(di-tert-butylphosphano)ferrocene, giving good yields of the corresponding arylboronates. The protocols tolerate a wide range of functional groups, includin...

Zusammenfassung:The cross-coupling of aryl arenesulfonates with dialkoxyboranes proceeded in the presence of Bu4NI and a catalytic amount of [Pd(dba)2]/1,1′-bis(di-tert-butylphosphano)ferrocene, giving good yields of the corresponding arylboronates. The protocols tolerate a wide range of functional groups, including ester, nitrile, and ketone.
